The best things you can do for sore muscles are light movement, temperature therapy, self-massage, and time. Most muscle soreness after exercise peaks between 24 and 72 hours, then resolves on its own within about five days as your body repairs the tiny tears in muscle fibers that caused the pain in the first place.
Those micro-tears sound alarming, but they’re actually how muscles grow. When you exercise hard, especially during movements where you’re lengthening a muscle under tension (think: lowering a heavy weight, running downhill, or the “down” phase of a squat), you create small amounts of damage in the thousands of tiny fibers that make up each muscle. Your body repairs those tears and builds the fibers back stronger. The soreness you feel is part of that inflammatory repair process.
Why Soreness Shows Up a Day or Two Later
This pattern has a name: delayed onset muscle soreness, or DOMS. It starts one to three days after your workout, not during it. That delay catches people off guard, especially when the soreness peaks on day two after a workout they thought wasn’t that intense. The inflammation and swelling around those micro-tears build gradually, which is why Tuesday’s leg workout can make stairs miserable on Thursday.
Soreness during or immediately after exercise is different. That’s typically from metabolic fatigue, the buildup of waste products in working muscles. It fades within an hour or so. DOMS is the deeper, achy stiffness that lingers.
Cold Therapy vs. Heat Therapy
Both work, but for different reasons. Cold is better for reducing inflammation, swelling, and fatigue. Heat increases blood flow to the muscles, which helps deliver nutrients for repair. Research from the American Physiological Society found that soaking in hot water (around 104°F) after intense exercise helped people recover muscle power output better than cold water immersion, while cold water (around 59°F) was more effective at relieving the raw soreness and swelling.
A practical approach: use cold in the first 24 hours when inflammation is peaking, then switch to heat on days two and three to promote blood flow and loosen stiffness. Ice packs for 15 to 20 minutes at a time work fine. A warm bath or heating pad for 15 to 20 minutes can ease that deep achiness once the initial swelling has calmed down.
Foam Rolling and Self-Massage
Foam rolling works by applying pressure to tight spots and adhesions in muscle tissue, helping loosen them and increase blood flow to the area. Roll each muscle group for about one minute, and don’t exceed two minutes on any single area. If you find a particularly tight knot, hold pressure on it for up to 30 seconds, but not longer. Going too hard or too long can actually make soreness worse the next day.
The best times to foam roll are immediately after a workout and again the following day during recovery. You don’t need to limit it to post-exercise, either. Rolling sore muscles on a rest day can provide noticeable relief.
Massage Guns
Percussive massage devices have solid evidence behind them. A controlled trial published in Frontiers in Public Health found that massage gun treatment significantly reduced pain, improved flexibility, and accelerated strength recovery in sore leg muscles. Longer sessions (about 4 minutes per muscle area) produced meaningfully better results than shorter ones (2.5 minutes per area). The key technique is to move the device slowly along the length of the muscle fiber with moderate, consistent pressure rather than jamming it into one spot.
Light Movement Helps More Than Rest
Complete rest feels instinctive when you’re sore, but gentle activity actually speeds recovery. Light walking, easy cycling, swimming, or a slow yoga flow increases circulation without adding more damage. This is often called “active recovery,” and it works because blood flow delivers oxygen and nutrients to damaged tissue while carrying away inflammatory waste products. You’re not trying to get a workout in. You’re just moving enough to keep things flowing.
What You Eat and Drink Matters
Tart cherry juice is one of the few foods with consistent research supporting its use for muscle soreness. The typical dose in studies is the equivalent of 50 to 60 cherries per serving, taken twice a day, once in the morning and once in the evening. Most study protocols have participants start drinking it several days before intense exercise and continue for two days after. The natural compounds in tart cherries help reduce inflammation and oxidative stress in damaged muscle tissue.
Beyond specific supplements, prioritizing protein after hard workouts gives your body the raw materials it needs to repair those micro-tears. Staying well hydrated also matters, since dehydration slows the delivery of nutrients to recovering muscles and can make soreness feel worse than it is.
Be Careful With Pain Relievers
Over-the-counter anti-inflammatory drugs like ibuprofen will reduce soreness, but there’s a trade-off. These medications work by blocking the enzymes that produce inflammation, and that same inflammation is part of how your muscles repair and grow. Evidence suggests that large doses of anti-inflammatories after intense exercise can reduce muscle protein building and slow functional recovery. Lower doses appear to have less of an effect, but the concern is real enough that regularly reaching for ibuprofen after every hard workout may be undermining your training gains over time.
If you’re sore enough that you need something to get through the day, a low dose occasionally is reasonable. But for routine post-workout soreness, the non-drug strategies above are better long-term choices.
When Soreness Isn’t Normal
Standard muscle soreness is uncomfortable but manageable. It doesn’t stop you from basic daily activities, and it improves steadily over a few days. There’s a more serious condition called rhabdomyolysis where muscle tissue breaks down so severely that it releases proteins into the bloodstream that can damage the kidneys.
The warning signs that set rhabdomyolysis apart from regular soreness, according to the CDC: pain that is more severe than you’d expect from the workout you did, dark urine that looks like tea or cola, and unusual weakness or fatigue where you can’t complete tasks you’d normally handle easily. Symptoms can appear hours or even days after the initial muscle injury, which makes the timing overlap with DOMS. You can’t distinguish the two by symptoms alone. A blood test is the only definitive way. If your urine turns dark or the pain feels disproportionate to your effort level, that warrants urgent medical attention.
